In the embodiment and 7 signal and its operating mechanism in ac cordance with the principles andpresenting the several features of our invention, illustrated herewith purely by way of example and not of limitation, a signal unit 'S is mounted on the interior of-a vehicle body B adjacent the rear wall 'Wl thereof and above the rear window -R for vertical up and down movements to and from its normaliinoperative position above and substantially, concealed from view from the ex'terior of the window R, (see Fig. 2) to its operative direction signal displaying position at and visible through this rear window R (seeFigs. l and 7) "from the exterior Qand'to the-rear of the vehicle. It to becle-arly under.- stood, however, that whilewe'happen'to have selected in our preferred form of the invenvtion the mounting of thelsignalfi-unit so that rrangement. of a calexpression 'of the 'several"features of our invention as illustrated in the accompanying drawings, the direction signaling unit Sgis mounted and supported in position on the interior of-the vehicle body for raising and lowering movementsbodily as unit' a vertical plan to and from the operative displayed position shown in I Fig. 1 where it is visible through the rear window R from the exterior of the vehicle so as to give the desired selected "direction, indicating signal. In the particular example hereof the mounting for the unit embodies amounting bracket and-supporting frame 10 which comprises the vertical spacedflegsr or plates "100' which are attached and. secured by "any suitable fastening means to and against the, rear wall W'ofthe vehicle body centrally above the rear window R thereof, and the horizontally and forwardly disposedi'top plate or platform I -O b-terminating at its forwardedge in the downwardly depending and :vertically disposed, plate 100 having the central yer-c tica'lly disposed jslo't 10d opening through the lower edge and extending upwardly therethroughto and terminating a distance below the top plate 10?). The top plate or platform 10?) ,of the'mounting bracket and frame 10 is cut-out inwardly a distance between the legs 10a to providethe central opening 106, as will be clear by reference to Figs. 5 and 6 of the drawings in particular.

The mounting bracket and supporting frame 10 carries and has the main operating shaft 11 rotatably journaled in the bearing 12 secured atthe 1 under side of the bracket top,

plate 10?), with the shaft horizontally disposed longitudinally ofand below top plate oriplatform 10b and substantially in a direction fore and aft or longitudinally of the vehicle body 13. The signal unit S is supported from shaft 11 and actuate d by such shaft through the medium of interconnecting actuating .mechanism so that upon rotation of such shaft the signalunit may be raised and lowered to and from its normal inoperative position of Fig. 2. In the particular example hereof this interconnecting raising and lowering mechanismbetween unit S. and the shaft 11 includesreferring particularly to Figs; 3 and 4 of the drawings thearms 14 pivotally and.

swingably mounted'for vertical rocking on the depending plates 100, respectively, by the pivot pins 15 providing horizontally disposed axes on which arms 14 rock. The arms 14 are disposed in this instance on the inner side of the plates 100 and extend outwardly therefrom and are provided at their outer ends wit-h the inwardly (rearwardly with respect to the vehicle body) extended horizontally disposed and substantially parallel stud shafts 16 which are fixed to the ends of arms 14 and form the medium by which signal unit S is mounted onand supported by the arms 14, The signal unit S includes an enclosing housing or casing 17 and journal boxes or bearings 18 and 19 are suitably secured and fixed on the upper vsideof the unit if casing adjacent the opposite ends thereof and the signal unit S is suported on and depends from theouter'spaced ends of oppositely extending arms 14 in horizontally disposed position therebelow and is bodily raisable and lowerable as a unit by vertically rocking the arms 14 on their; pivot pins 15. I The journal box 18permits the necessary play between the stud shaft 16 .journaled therein and the units to-care for the variations, in distance betweenjthe-ends ofarms14 in their raised and lowered positionsx-lvhen arms 14 are swung downwardly to their positions of F gs.

' 3 and 5 the signal unit S is lowered thereby .to

its operative position of Fig; 1, and when these arms, are, swung upwardly to their raised positions of Fig. 4,'th'elsignal}unit-S is raised to the normal inoperative.substantially concealed position of Fig. '2. I I. The signal unit S through the arms '14 is normally maintained in its raised inoperative position by suitablemeans such as the coil tension or retractile springs '20 secured" at their upper ends to the spaced fingers 21 extending 'rearwardly from the topplate 10b of bracket 10 adjacent the opposite edgesof such top plate, and. at their lower ends at-,

' tachedand secured'to suitable .pins .22 car-.;

ried by the armsv 14, respectively at points on the arms intermediate the pivot pins 151' and the outer ends of vthefarms. These springs normally exert a force or tension on The mechanism for swinging or rocking the arms .14v downwardly against springs '20 to lower the signal unit S, includes in the present example a crank 23 fixed to'the main operating shaft 11 between the inner end of this shaft and the depending plates of the bracketlO. A cam block or wedge member. 24 is vertically slidably mountedin the slot 10d formed" between -;the depending plateslOc. .by opposite edge,grooves-..24a in this slot (see Fig. 2) into which the opposite edges of slot 1OcZ are slidably received with block 100?, confined against lateral displace-T ment. A link 25 is pivotally connected at one end to a pin 26 on the cam block 24 adjacent its lower edge and at its opposite end is pivotally mounted on a pin 27 carried by the crank arm 23 adjacent its outer free end. Thus by rotating the main operatingshaft 11 crank arm 23 is rotated and through the links 25 vertically reoiprocates'the cam block 24 inthe slot 10d. The inner end of the opposite arms 14 are provided with the inwardly and upwardly extending heads 28 whichtermh note in the inwardly extended and curved or? rounded cam surfaces 29, whichv are so arranged as to be engaged and forced apartby the cam'block 24 when, the latter is raised, so that the arms 14 are swung downwardly to lower slgnal llIllil'S to its operative position and 5 of the drawings in particular; ,When the-shaft 11 is rotated to move cam block 24 downwardly in the slot 10d, the'fcamblock 9U. the arms :14 to swingthe same upwardly and 1 maintain the arms in normal raised position shown in Fig. 4, and to lower the signal unit S arms 14 must be swung downwardly against 1 and to' expand the contractile springs 20. l

with the block 24 at its'lim'it of upwardmove. 'ment as will be clear by reference to Figs. 3

moves from between cam surfaces 29 f arms 14 and releases these arms for upward swing,- thereofthrough theaction of the contrac-' tile. springs 20, with the result that these. springs perform a retrieving-action and automatically swing arms 14 upwardly to'raise:

the signal unit S to its normal inoperative position as shown by Figs. 2 and. 4- in part-i'cular; On-the' other hand with the cam block 24 in its lowered position of Fig. l, upon actuation of shaft 11 in the proper di rection, block24. is raised upwardly between the inwardly extending heads 28' and cam surfaces 29 of the arms 14 so that these heads are forced apart and cause downward swing-1 ing of arms 1 f against springs 20 to lower the signal unit S to'its operative position.

An operating. mechanism selectively under the control ofithe driver of the vehicle, either through. directmanual actuation or actuation through and by the steering mechanism of. the vehicle, is provided for. actuating: the main shaft 11 to raise and lower signalunit'S from and to its operative signal displaying and direction indicating position VlSlble through the rear window of the vehicle body; In

the particular example hereof we happen to show a manually controlled operating mechanism, although it is to be understood that the invention contemplates and includes the operative connection and coupling of such mechanism with the steering mechanism (not shown) ofthe vehicle for actuation by, such .mechanism as the same is controlled to turn the vehicle to the right or the left.

This

manually controlled operating mechanism in cludes a shaft 30 disposed longitudinally of" and alongthe top of the Vehicle," preferably although not necessarily substantially alongi the longitudinal or fore and aft axes of the vehicle, along and adjacent the top of the vehicle body B, which shaft at its forward end is journaled in a suitable bearing 31 secured to the top of the vehicle and extending. rearwardly from such bearing tothe forwarder inner end of the signal actuating shaft 11' to which it is coupled by means of the universal joint or coupling 32, all asclearly disclosed in Figs. 1 and 2 of'the drawings. Theshaft 30 extends forwardly or inwardly a distance beyond bearing 31 and is-there provided with an operating lever or handle 33 depending therefrom and disposed in such position asto be readily and naturally grasped by the hand of the vehicle driver for lateral swinging to rotate shaft 303. The handle 33 is so mountedin relative position on shaft'30that with shaft 30 and the signal operating shaft 11 in positions rotated with the signalunit;

S in its normal raised, inoperative and sub stantially concealed positio-m the handle 33 depends from shaft 30in. a substantially ver tical position such-as shownin full linesby Figs; land 20!. and in dotted lines by Figs. 1. and 1a.. With this selective 'IIlilIlllLlCOl'ltlOl or operating 7 mechanism, when handle 33- is swung laterally'toieitherthe right or the left from. its normal vertically disposed and signal inoperative position, the shaft3'0 is rotated to rotate shaft ll to in turn raise cam block 24- andflthrough the mechanism hereinbefore described cause the lowering of the signal unit S to its operative signal dis playingposition,where it is locked against displacement until further positive'manual actuationof handle 33 back to its normal: neuetral vertically disposedpositi'on.

The signal unitfS I of the example hereof is formed'jby' a substantially elongated casing or box like structure having closed opposite end wallsin the form of flanged caps=34,

out to provide the double end directionindi eating symbol or arrow shaped opening 37 therethrough, which is coveredbya suitable transparent material, preferably red in color such asa sheet or plate of red glassor the likeLtranspa-rent material 38. In this-manner a colored double headed arrow is" formed-in the wall pointing in opposite directionslongitudinally, of thecasing, that is to the right and to the left of the vehicle. A pair of' spaced: slides-or shutters 39 are mounted for reciprocation longitudinally of the front wall 35 'on'the exterior thereof, in the paths 7 of upper and lower guides 40 disposedalongthe upper and lower edges of wall 35 adja cent opposite ends thereof, respectively. These slides 'orshutters 39 mountedfin the guides {l0 are each formed with a cut away portion ll in alignment with the arrow shaped opening 37 and the oppositearrow heads thereof, and areso spaced apart and joined" by the connecting rod or link 42for'movement in unison longitudinally of'the signal unit S,'thatwith one slide at its" limit of outward movement the cut away portion thereof exposes the adjacent head of the arrow 37 while the opposite slide or' shutter is moved inwardly to a position over and masking the adjacent head of the arrow37 In thismaner the arrow 37 appears as a single headed arrow ,pointing in the direction of the exposed head, as will be clearby reference to Fig. 5. By reciprocatingthe slides or shutters 39 in-the reve'rse'direction the exposed" arrow head is covered up by the adjacent-slide 39,. while the masked headthen becomes exposed through the cut out 41 in the adjacent shutter 39 to form iLH fiPIO-Wl pointmg n'the reverse direction.
